CGNNECTEE FOR CHAIN LINKS.

Application filed April 27, 192?. Serial No. 188,933.

This invention .rela tes to an improvedconnecter for the ends oi bracelets or chain links; and has for its object to provide a connector of this character by which the terminal links of the bracelet may be readily connected to and disconnected from each other through the medium of a pivoted hook memher.

A further object of the invention is the provision of a connectcr hook member pivot allv mounted near one end. of the links. the hoiik being provided with an operating arm ar ringed to swing outwardly relative to the front of the link on which it is mounted to move the hook to open or released position and back to close the hook.

A still further object of the invention is the provision of a bar or other elementon the adjacent link to receive this connecting hook whereby the two ends of the chain may be readily connected together and disconnected from each other.

A still further object of the invention is the provision of a pair of operating arms for the hook which are arranged to extend along opposite sides of the link the arms being connected by a cross bar over the top of the link, whereby it may be readily engaged for moving the hook to open and closed positions.

lVit-h these and other objects in View, the invention consists of certain novel features of construction, as will be more fully de-v scribed, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a view of the bracelet or:- tcnded.

Figure 2 is a perspective view of one of the links showing the attaching bar at the end thereof.

Figure 3 is a perspective view of the hookcarrying link showing the operating arm raised and the hook in open position.

Figure 4. is a plan view partly in section illustrating the way the hook is mounted on the box-shaped link.

Figure 5 is a side elevation partly in section showing the two links as connected together by my improved connecter.

Figure 6 is a sectional View showing how the undercut portion of the link permits a relative swinging action of these connected links.

it is found in practice of advantage to provide in a chain or bracelet particular y in abracelet to be able to disconnect the links near its middle portion instead of be ing obliged to disconnect the links tom the hail of the wrist watch to which its opposite ends are attached, and to accomplish this in a simple and effective way, I have pivoted hook member onto the'end of one of the links and arranged a pair of operating arms to extend along opposite sides of the link, the arn'is being connected together over the front of the link so as to permit the hook to be readily operated and the bracelet separated at its middle portion to be removed from the arm oi? the wearer; and the following is a detailcc description of the present embodiment oil my invention and showingone means by which these advantageous results may be accomplished:

With reference to the drawings, 10 designates one of the middle links of the bracelet or chain which as herein shown is of the box type of link, the link being preferably at its end as at 11 and undercut slightly is provided with a connecting cross bar 12. The other adjacent middle link 13 of the chain or bracelet is herein shown as being of the box type of link and is also undercut slightly at 14 to permit a relative swinging motion and a pivot pin 15 extends across its end portion carrying a hook 1b. The ends oi this pivot pin are arranged to extend through the opposite side walls '17 of the link and to the extemling ends are fixed the arms 18 which are arranged to lie along the opposite sides of the link, their outer ends being connected by the cross bar 19 which lies closely against the front face of the link when the hook is in closed position so that when the hook is in closed position this bar may be easily engaged and lifted to swing the hook to open position, as illus trated at 19 in Figure 5 which position swings the hook out of engagement with the bar 12 and releases the two adjacent links to be separated one from the other, and to connect these links it is only necessary to move the opened hook into engagement with the cross bar 12 and then swing the arms cept-ible, the invention. being 19 down until the cross bar rests against the upper face of the link.

The device is extremely simple and practical in construction and isieilective'in its operation. v i

The foregoing description is directed solelytowards the construction illustrated, desire it to be understood that l reserve the PllVllL f" ing to all the mechanicatchangres to which the device is susdefined and limited only by the terms of the appended claims. i

I claim:

1. A connector for chain links coinprisi a box-shaped link, a pivot pin extending through the sidewalls fixed to the pin between said side Walls, and

' through the side 7 fixed to the pin between said side Walls,

ing. a box-shaped link, 7 V 7 ing through tllOSlClQ Walls of the l1nk,-a

an'operatingarn'i connected to the pin to extend along the outsideall of the link.

2. A connector for chain links comprishook liked to the pin between said side Walls, an operating arm connected to the pin to extend along the outsidewall 01 the link, and having an operating'member extending over the front of the link.

A connecter for chain links comprising a box-shaped link, a pivot pin extending Walls ot the link, a hook operating arm connected to the pinto extend along the outside Wall of the linkhaving an operating member extending over they front ofthe link, and a cooperating hook-rece1v1ng member on the end of the'adjacent link.

4:. A connecter torchainlinks comprising a box-shaped link, a pivot pin extending: through the side Walls of the llnk, a hook fixed to the pin between said sidewalls, an operatingarm connected to the pinto ex but I of the link, a hook a pivot pin extending, a hook having a mouth open generally upwardly d pivoted to one of the links and an operatin armextendlng along said link attached to said hook at its pivot to swing the same to open position by an upward movement thereof, and a hook receiving element'on an adjacent link. 7

6. A connector for chain links comprising a box-shaped terminal link, a hook pivoted at one end of the link, a'pair of operating.

arms secured to the hook at its pivot and arranged to extend along the-opposite sides of the link and connected together over the frontof the link by a cross arm.

7 A connector for chain links comprising aboX-shaped terminal link, a hook pivoted at oneend ofthe iink, a pair of operating arms secured tothe hook at its pivot and arranged to'extend along the opposite sides of the link-and connected together over the front of the llnk by a cross a1m,.and.a detent on said armsto releasably retain them and the hook in operating position.

. 8. A connecter for chain links comprising a box-shapedterminal link, an arm pivotally. connected to the link,a hook at one end of said arm, means for pivotally mount lng said arm and hook to the terminal link in position to cause said arm fto extend.

along the side of said terminallink when thehook is in closed position, and a hookreceining element on an adjacent link;

In testimony Whereotl affix my signature.
